Hello, café. Recently I asked about tcp server libraries [1] and there was only one answer haskell-scallable-server [2], but in that package there was some dependencies and server logic that are not good for my task. So I decided to make a library with skeletons for different types of tcp servers and a basic library to make server [3]. Now there is only warp based (simplified) tcp server. Main logic is: * handle new connection and start iteratee green thread * enumerator (library side) reads socket and send data into enumeratee (application side) * enumeratee consumes input and produces server command (now simply output) and push it into iteratee (server side) * iteratee server side reads command and performs action (now simply output command) It gives application possibility to store state in enumerator. My questions to community: 1). can you help to make code better ;) maybe there are some stupid mistakes 2). is there any ideas what thing can be add to the server to make it reusable And another thing that I want to add other types of server e.g. single threaded, with workers pool, or other types. And I want to ask what types of servers will be effective in haskell.
